Pneumatic Actuator

Key Features

-Direction of rotation can be optionally changed from clockwise (CW)to anti clockwise(CCW)
-End-position sensor and limit switch box can be mounted directly to the actuator
-Suitable for manual on site use,as well as automatic operation
-Port pattern to Namur VDI/VDE 3845 for mounting solenoid valves.
-Highly corrosion resistant

1.Actuator body

According to the different requirements,the extruded aluminum alloy ASTM6005 body can be treated with hard anodized,powder polyester painted(different colors is available) PTFE or Nickel plated.

2.End Caps

Die-casting aluminum powder polyester painted in different colors, PTFE or Nickel plated.

3.Pistons

The twin rack pistons are made from Die-casting aluminum treated with hard anodized or made from cast steel with galvanization.
A symmetric mounting position, long cycle life and fast operation, reversing rotation by simply inverting the pistons.

4.Indicator

The position indicator according NAMUR standard is convenient for mounting accessories such as Limit Switch Box,Position and so on.

5.Pinion

The pinion is high-precision and integrative, made from nickel-alloy steel,fulI confirm to the latest standards of ISO5211,DIN3337 and NAMUR,The
dimensions can be customized and a stainless steel pinion is available.

6.Travel adjustment

The two independent external travel stop adjustment bolts can be adjusted ±5° at both open and closed directions easily and precisely.

7.High performance springs

Pre-loaded, coated springs are made from the high quality material for resistant to corrosion and longer service life, which can be demounted safely
and conveniently to satisfy different requirements of torque by changing the quantity of springs.

8.O-rings

NBR O-rings provide trouble-free operation at standard temperature ranges. For high and low temperature applications Viton or Silicone.

9.Bearings & Guides

Bearings and guides are made from low friction, long-life compound material to avoid the direct contact between metals.The maintenance and replacement is easy and convenient

For the sizing examples in this website we will use a rack and pinion actuator to explain how to size doubleacting and single acting quarter turn actuators.
